词族故事
ONE STORY, MANY NUANCES
用一个有意义的场景串起这组词和它们的细微差别。
原创 · 山路转弯处
When her father’s illness made time feel suddenly scarce, Mira had to decline the promotion that would have taken her abroad. She was disinclined to call it courage; staying meant tending old gardens and unfinished conversations. Yet with quiet discipline, she learned that an ordinary life can incline toward love, even after loss has changed its shape.
父亲生病后，时间忽然显得所剩无几，米拉只得拒绝那份会把她带往异国的晋升。她不愿把这称作勇气；留下来，意味着照料荒芜的花园，也拾起那些未完的谈话。然而凭着安静的自律，她终于明白：即使失去改变了爱的形状，平凡的生活仍能向爱倾斜。

ONE LINE TO KEEP
最后用一条线索收束整组关系。
decline与incline都围绕倾斜及由此产生的方向或倾向，disincline则由 dis- 加 incline 表示不倾向；discipline虽然涉及训练和约束，但来自独立的 disciplin 词源。
